It’s a bit of a sledgehammer approach, but a Nuc with Proxmox is pretty excellent. You can even use 10gbe via thunderbolt (or the pci slot on the larger Nucs).
So far I'm pretty impressed with my Rk3588 board, 8gb ram, and dual 2.5gbe.
It's a bit more than half as fast as my quad core/8 thread xeon desktop, but that's abotu where I'd expect one of the cheaper x86 NUC/Mini PC/Thin clients to land.
